How to Propagate Basil in Water
Choose a Healthy Basil Plant. Select a mature basil plant with no signs of disease or pests. Look for stems that are at least four inches long and have several sets of leaves.
Cut the Stem. Using scissors or pruning shears, snip a 4- to 6-inch stem right below a leaf node, which is where leaves grow from the stem. Remove the leaves from the bottom two inches of the cutting.
Place in Water. Fill a glass or jar with lukewarm water and place the cutting in it. Make sure the leaf nodes are submerged, but keep the leaves above the waterline to prevent rot.
Add Light. Place the jar in a bright, indirect light location. A windowsill is a great option. Avoid direct sunlight, which can overheat the water and stress the cutting.
Change the Water Regularly. Replace the water every two to three days to keep it fresh. This helps prevent bacterial growth and encourages healthy root development.
Wait for Roots to Grow. Roots will start forming after about seven to 14 days. Wait until the roots are at least 2 inches long before transplanting.
Transplant to Soil. Once the roots are well-developed, plant the cutting in a small pot with moist, well-draining soil. Water thoroughly and keep in indirect light for a few days to help it adjust.

How to Propagate Basil in Soil
Prepare the Cutting. Just like with water propagation, cut a 4- to 6-inch stem below a leaf node and remove the lower leaves.
Dip in Rooting Hormone Powder. For faster root development, dip the cut end of the stem in rooting hormone powder. This step is optional, but it helps with growth.
Plant in Potting Mix. Fill a small pot with a light, well-draining potting mix. Make a hole in the soil and insert the cutting about two inches deep. Gently press the soil around the stem to make it firm.
Water Lightly. Wet the soil, but don't soak it. Basil cuttings are prone to rot if overwatered, so ensure the pot has good drainage.
Create a Humid Environment. Cover the pot with a plastic bag or a clear plastic dome to retain humidity. Make sure the cover doesn’t touch the leaves.
Provide Indirect Light. Place the pot in a warm area with indirect light. Avoid direct sun until the plant is well-established.
Check for Root Growth. After two to three weeks, gently tug on the cutting. Roots have formed if you feel any resistance when tugging. You can remove the plastic cover and care for it like a regular mature plant.
Tip
Use a spray bottle to mist the soil and leaves lightly for the first week to maintain humidity. Use a clear container to make it easier to monitor root growth and water quality.
When to Propagate Basil
The best time to propagate basil is during the warm growing season, typically between late spring through summer. Basil thrives in temperatures between 70°F to 85°F and cuttings root more quickly in warm, humid conditions.
Avoid propagating in cold or dry weather, as the cuttings may struggle to root or become stressed. If you're growing basil indoors, you can propagate year-round as long as you provide enough warmth and light.
"Basil is relatively easy to grow from seed, or you can use the traditional method of taking cuttings and putting them in a propagation mix," Annette Hird, horticulturalist and gardening expert, says. "My favorite mix that I make myself is relatively equal parts of coco coir and vermiculite."
Basil Propagation Tips
Proper Lighting Matters: Basil cuttings need bright, indirect light. Too much direct sun can scorch them, while too little light slows root growth.
Avoid Overwatering: Whether in water or soil, too much moisture can lead to rot. Keep water fresh and soil damp but not too wet.
Use Clean Gardening Tools: Always use sterilized scissors or shears to prevent introducing disease to cuttings.
Use the Right Soil: A light, well-draining potting mix is ideal for transplanting rooted cuttings.
Change Positions: If propagating multiple cuttings, rotate their position in the light to ensure even growth.
Keep Things Warm: Basil loves warmth. Keep cuttings in a spot that stays above 70°F for best results.
Experiment With Both Water and Soil: Try both water and soil propagation to see which works best for your environment and preferences.
